Abstract: A paste for a reference electrode according to an embodiment of the present disclosure includes silver chloride powder and a carbon-based conductive material. The carbon-based conductive material may include at least one compound selected from the group consisting of carbon nanotubes, graphite, graphene, and carbon black. The reference electrode formed of the paste for a reference electrode according to an exemplary embodiment may provide improved mechanical properties and electrochemical properties.

Abstract: A display device includes a pixel. The pixel is electrically connected to a first power line, a second power line, and a data line. The pixel includes a first transistor, and a capacitor electrically connected between a gate electrode of the first transistor and an electrode of the first transistor. In a plan view, the data line extends in a second direction. The first power line extends in a first direction intersecting the second direction and overlaps the data line and the gate electrode of the first transistor. The second power line extends in the second direction, overlaps the data line, and overlaps the gate electrode of the first transistor.

Abstract: Disclosed herein is an antireflective photocatalyst composition including a titanium dioxide-based photocatalyst, a binder, water, and alcohol, and a substrate using the composition. The antireflective photocatalyst composition is advantageous in that, when it is applied to a glass substrate, such as a glass antireflective film for a solar cell or a glass illuminator, it can prevent incident light energy from scattering and improve optical transmissivity, and in that it decomposes pollutants due to the dual action of harmful gas decomposition and self-purification, which are specific characteristics of a photocatalyst.
